power dissipation from this path always, just when we off the rail
(disable rail or when go to shutdown so that the voltage output can
go down faster).
Should we add "unsigned en_discharge:1" in regulator init data but
did not get how core driver can use this flag specially when
shutdown?
This is pretty unusual for such hardware. Normally there's something in
the digital block so that the discharge is only enabled if the regulator
is disabled, if it's enabled then the discharge would automatically be
taken off since actively discharging while enabled doesn't make sense
and may in fact be actively harmful.
If the hardware doesn't do that then I'd expect the driver to take care
of this if it implements the framework feature (once the framework
feature is added).
